To my understanding the Turpin hen box included the handle on the box has or so has the tophat included in the lid. I havent had the pleasure to see nor run many orginal Turpin call (old ones). I have been told by a couple people that have orginal boxes that the boxes i build is different than others. ie. Radius, Running style, Lid Radius. They run slimlar to a long box with the yee yalk of a Tupin style calls. They do run different than other calls but if you take the time to learn how they run and what can be done with then , well the picture speak for the calls.
